Narrative:

Our clearance was to depart the hrmns 2 RNAV departure off of 10L. I was the pilot flying. We had completed our preflight duties and the captain called for the before start checklist. After the captain completed his briefing; I began with the departure briefing reading off each fix and crossing restrictions from the chart. During that time; the agent dropped off the load sheet and began to thank the captain for helping with wheelchairs. When calling for push; ground said to expect runway 10L at tango. I got the new numbers after push and we then completed the before taxi checklist. Once airborne; LNAV disengaged so I called for LNAV at 400 ft and the aircraft started directing a right turn toward pegty; the first fix off of the 28's. I noticed shortly after that that we did not have the correct points in front of us. I realized that the FMC had the waypoints for the 28's programmed instead of the 10's. The captain tired to input the next waypoints; but we had already passed each of the fixes he entered. Tower asked us where we were going and that we did not follow the appropriate course. He asked us to contact departure and we were then given direct hrmns. I do believe I checked the route and legs page before push; because I normally do. While I was reading the departure briefing; we were distracted by the agent. The captain may have missed crosschecking the points with the FMC. Whenever distracted; I should start whatever checklist or briefing over again.
